Take the stereo all the way out and hook the black wire to the negative terminal and the yellow and the red wire to the positive terminal on a charged car battey. If it still does not turn on you may have fuse in the back of the deck. If not it's probably fried.

Make sure you do have a good ground.
If none of these solutions work you most likely have a bad system.
